I mean uncompressed...

gah. I think this issue is tied to GzipFile's being a wrapper around a normal file. Will try to fix it.

Okay - it looked to me like it was happening even if I didn't do anything with mausput.gz in simulate_mice.py - so I assumed there was some old hard coded stuff that hasn't been cleaned up properly. I didn't dig.

wait, what's the issue? there should be a default output and you'll always need output. I moved the default to .gz then back from .gz after it wasn't working.

• Code is up to date.
• I remove mausput.gz
• I run simulate_mice.py
• mausput.gz has appeared
• but the simulate_mice.py output file name is simulation.out - why is it making a mausput.gz file as well as a simulation.out file?

Also I was having trouble gunzipping mausput.gz when the output file name was mausput.gz - may be unrelated. I notice now I have changed the output file name I can do a gunzip to return an empty file.
